Updated NRobot and DA

The version of my NRobot entry I previously posted had a little flaw -
if (due to security restrictions or any other reason) any robot teams
fail to load, it turned into a very complicated
spin-in-a-circle-and-do-nothing bot. That scenario happened in the
default configuration, because LatteBot is prohibited from running by
the security sandbox. This version has the bug fixed.

I also uploaded a new version (0.21) of NRobot, to fix a few
compilation issues on Linux and push some other minor tweaks that have
been made since 0.20. This doesn't include the 3D frontend - I belive I
need to reimplement Microsoft's Mesh3DObjects sample class, because it
comes with no explicit license, before I can release that. Even if it
had been included, you'd need the WinFX alpha toolkit and the .NET
framework 2.0 beta to run it anyway.

Anyone want to try implementing a 3D frontend using OpenGL or some other freely-implemented API instead?

I feel dirty

I believe in Open Source for technical reasons, but I also believe in
Free Software for ethical ones. I make a point not to choose one of
these philosophies over the other, but instead to emphasise how great
it is that the same rules - epitomized by the DFSG or OSD - are worth following for two entirely different reasons.

Anyway, while I don't always live up to the goal of never using
non-free software, when programming for personal reasons I have at
least aimed for the goal that there should be a not-so-distant prospect
that what I write can run on an entirely Free system.

Thus when I wrote nrdo, its initial versions may have depended on Java
and Oracle, but I was entirely confident that Classpath and company
would eventually be able to run it, and that a Postgres backend could
be developed (both of these happened). When I ported it to C# it was
(quite apart from being necessary for my job) under the assumption that
it would run under mono in the near future (it does, as far as I know,
although it's been a long time since I tested it and mono has changed a
lot since).

When I wrote NRobot, running under mono was a primary goal, although I test it less often than I would like.

Even cmScribe, which is proprietary software that I'm paid to work on,
I fully expect to be ported to mono and Postgres eventually (if only
because it will make our company's story about hosting cheaper - no SQL
Server license required!).

But I've succumbed to temptation and written something that has no
prospect of running on a free system anytime soon. Apparently Microsoft
has said that it does not believe it's possible for the mono project to
clone its new Avalon GUI toolkit and Indigo messaging system without
licensing some "Intellectual Property" from them, and apparently (at
least in the case of Indigo) the mono people have accepted this and are
not currently planning Avalon or Indigo clones.

Which is a shame, because it means that I've violated my principle of
only doing stuff which will ultimately be runnable on Free systems, and
means that mono users won't be able to see this:
